Application led March 10,1885.

t, To @ZZ whoml it my'concerm Be it known that I, FREDERICK SEDGWICK, of Chicago, in thecouu'ty of Cook and State of Illinois, have invented certain new and useful Improvements in Electric Safe-Lock and Bolt- Moving Mechanism, Aof which the following is a description, reference being had to the accompanying drawings,in which- Figure l is a vertical sectional view of an air'chaniber orcase, showing the lock mech-v anism therein as viewed from thefinside of the safe, and connected with the bolt-work, together with a front view of a dial for operating the same. Fig. 2 is a plan vView of said lock and bolt-moving mechanism, showing a horizontal section of the door to which the same is attached. Fig. 3 is a back view of said case,` showing the auxiliary mechanism attached thereto forretracting the bolt-work. Fig. 4 is a vertical sectional view of said door and an end view of said case as seen in the direction indicated by the arrow shown in Fig. l; and Fig. 5 is a central vertical sectional view, in detail, of a portion of the cylinder, showing the construction of the valve and ports.

Like letters in the different iigures indicate like parts.

In an application herewith filed by'me for` Letters Patent for an improvedelectric lock and bolt-moving mechanism I have shown an electric permutation-lock the bolt of which is attached to a suitable valve, and isadapted by its movement to release a volume of compressed air to act upon a piston, and thus actu'- ate the bolt-work. v

The object of my invention herein `is to connect with said lock and bolt-moving device an auxiliary mechanism which maybe employed by electrical means from without the safe to retract the bolt-work in the event of the failure of said compressed air to effect the desired result, said auxiliary mechanism` being rendered inoperative by blocking the same or breaking the circuit therewith at all times except when thelllock-bolt is retracted, which said combined mechanism is hereinafter more particularly described and claimed.

In the drawings, A represents an air-tight compartment or case, which may be removably attached by means of bolts or screws, or otherwise, to the safe-door B. Said compart- Seiial No. 158,210. (No model.)

ment is provided with a removable face-plate, a, Figs. 2 and 4, attached thereto by Ineans of screws a', the connecting joint thereof being hermetically sealed. Connected with said com partment, as clearly shown in the drawings, is an air-pump, C, constructed substantially as shown, or in any Well-known manner, and having a valve, c, Fig. I, in the bottom of its cylinder, so that upon operating said pump air may be forced or compressed within the chamber A, from which the same can only be released in the manner hereinafter set forth. Vithin said chamber A, and attached to the case thereof, as shown in Fig. l, I place an electro-magnetic per1nutation-lock,consistconcentrically to a revolving armature, E, connected by suitable gears and other mechanism with a series of `tumblers and a lock- `bolt,F. Said magnets are connected by means of wires d d d d and ci rcuit-wire d, as clearly shown in the drawings, with a suitable battery-cup, G, and a dial or circuit-breaking mechanism, H, outside of the safe,whereby and from whence said magnets maybe excited in regular consecutive order,the tumblers manipulated, and the bolt F thrown or retracted at will, all of which mechanism is fully and accurately described in an application forLetters Patent filed by me in the Patent Office on theZOth day of August, A. D. 1384, and to whi'ch'I herein make no claim. Vithin said compartment A, I likewise place a cylinder, J, having a suitable piston, j, Fig. 5, the rod j of which passes through the case A, and is rigidly connected to the bolt-bar Ii y,by rivets orboltsjk, Fig. 1. Said cylinder' is provided with induction-ports jz js, Fig. 5, communieating with the compartment A, which are opened and closed by means of a two-way cock lor valve, L, having portsl l', so placed that a partial revolution of said valve serves to open one port while the other is closed, said ports 'l Z communicating with openings j* j, Fig. 5, in the outer shell. A notch,V Z2, in the plug of said yvalve serves to alternately connect said ports with an exhaust-pipe, Z3, Fig. 5, leading to the outside of the case A. Rigidly connected with said valve L is a crank, Z, Fig. I, which is loosely or pivotally attached to the reciprocating bar F, so that-the movement of ing of a series of electromagnets, D, arranged IOO the latter back and fort-h may partially rotate said valve L and open one and close the other of said ports, respectively, thus permitting the compressed air within the case A to ilow into said cylinder behind or in front of the piston j, and by the movement of the latter throw or retract the bolt-bar K, as described.

The compartment or case Ais provided with studs or projections c, Figs. 2, ,and ,which rest against the door B, thereby leaving a space between said door and case, within which I place an electro-magnet, M, (shown in the figures last named,)in i'ront of the poles of which loosely pivoted, as shown, a depending armature, N, having a gravity-pawl, a, Fig. 3, loosely attached to its lower end, and preferably supported in a horizontal position by means ol' a stud, a, adapted to e11- gage a ratchet-wheel, 0, (better shown in Fig. 3,) which is prevented from moving, except when desired, byu spring-stop, a?, attached to said case.

Attached to the ratchet-wheel O, and upon the same axis, I provide a pinion, o, adapted to engage with one of a series of gears, 12]), Q, q, and R, the latter of which is connected, prel'cra bly by a pitman, R', to the bolt-bar l. 'lhe magnet M is connected by an insulated wire, yat, running through the door B, having a binding-post, 111/, interposed, to a push-button or circuit-breaker, S, constructed in the usual way, and preferably attached to the plate HQ Figs. l and L1, to which the dial Il. is attached. The terminal wire m of said magnet M (better shown in Fig. l) is carried to a binding-post, in, vattached to the case A, and insulated therefrom, from whence said wire is connected by a Screw, m, Fig. l, to a spring, m5, insulated from the lock-case by a vulcanite block, m6. Said spring and lock case, rcspectively, are provided with contact-points ml m5, which are normally separated from each other, the spring being so adjusted that when the lock-bolt F is retracted or in the opposite position from that shown in Fig. l the spring is bent thereby and the contact-points ml mR brought together, thus making a metallic or electrical connection from the wire m2 with the case A, and thence through the safe-door to a binding-post, t, Fig. et, connected by a wire, i', having connection with a battery, T, with the push-button S. rlhus it will be seen that so long as the bolt F is thrown,leaving the spring m5 in its normal position, the circuit is broken with the magnet M, while the reverse movement of said bolt F connects the points onT on and enables the magnet M to be excited by means of the button S, the manipulation of which causes the pawl a to engage the ratchetwheel O, and thus actuate the train of wheels described. Said mechanism iirst above described maybe operated as follows: Avolume of air is compressed within the compartmentA by means of the pump C, after which the door B is closed and the dial H rotated, thereby actuating the bar F,and with it the crank Z,

which opens the port j?, thus allowingr a portion of the compressed air within the compartment A to enter behind the pistonj and force the same forward, resulting in the movement of the bolt-bar K and the locking ofthe sal'e.

Upon manipulating the combination by means of the dial H the bar F is retracted, which reverses the movement of the valve L, thus permitting the escape, through the duct 01 pipe Z3, of the compressed air behind the pistonj,and allowing an influx in front thereof through the port j, which rctracts the boltwork and enables the safe to be again opened.

So long as the compressed-air mechanism irst above described is effective, said auxiliary mechanism may remain at rest, a slot, r, Figs. l and 3, being made in the bolt-bar LIC, with which the pitman R is loosely connected,

which enables said bar to be thrown and re! tracted by the piston-rod j, without moving said pitman, to permit which movement the wheel R should be in the position substantially as shown in Fig. 3. Should said conipressed air fail to move the bolt work when the lock-bolt F is retracted, said auxiliary mechanism may then be brought into requisition and operated follows: Upon pressing the button S the magnet M is excited and attracts the armature N, thus actuating the pawl n and moving the ratchetwheel O one notch. As soon as the circuit is broken by releasing the button, the arm N, by virtue of its own gravity, assumes a vertical position au d draws the pawl a back in position for a second engagement, so that by manipulating the button S the wheel R is caused to make a hal f-revolution, thus retracting the bolt-work.
